Pruning

Water
The Japanese Iris or 'Southern Son' requires evenly moist soil, especially during the growing season. During the first year, it's crucial to keep the soil consistently moist without causing waterlogged conditions. Water deeply once a week with about one to two gallons, depending on the weather and soil drainage. Increase watering to twice a week during hot, dry spells. However, in the winter when the plant is dormant, reduce watering significantly to prevent root rot.
Light
Japanese Iris thrives in full sun to partial shade. The ideal spot for 'Southern Son' is where it can receive direct sunlight for at least six hours a day. However, in hotter climates, they benefit from afternoon shade to protect them from the intense heat of the late day sun.
Temperature
'Southern Son' Japanese Iris prefers moderate temperatures and will thrive when the temperature ranges from 50 to 75 degrees Fahrenheit. The plant can withstand temperatures as low as 5 degrees Fahrenheit but may suffer damage if temperatures fall below this. Ideal growing conditions are cool nights and warm days within the preferred temperature range.
Pruning
Pruning Japanese Iris, 'Southern Son,' helps maintain plant health by removing dead or diseased foliage. After blooming, cut flower stems down to the base, but leave the foliage to continue to collect sunlight. In late fall or early winter, remove any dead leaves and cut back foliage to a few inches above the ground. Prune annually to ensure vigor and prepare the plant for the next growing season.
Cleaning
As needed
Soil
Japanese iris prefers acidic to neutral soil with a pH of around 5.5 to 7.0. For best growth, mix peat moss, compost, and a little sand to ensure high organic content and good drainage. Mulch to retain moisture.
Repotting
Japanese iris should be repotted every 2-3 years or when clumps become overcrowded to maintain vigor and flower quality.
Humidity & Misting
Japanese iris thrives in high humidity; aim for levels around 75-80% which mimics its natural boggy habitat conditions.
Suitable locations
- Indoor
  Ensure high humidity, indirect light, and keep the soil moist.
- Outdoor
  Plant in moist, acidic soil in a sunny or part-shade spot.
- Hardiness zone
  4-9 USDA
Life cycle
The life of the Japanese Iris 'Southern Son' begins with seed germination, where seeds require a period of cold stratification before they sprout. After germination, the seedling grows and develops into a young plant with characteristic slender, grass-like foliage. The plant continues to grow and establish a strong root system, typically forming rhizomes that can spread underground. Once mature, which could take a couple of years, the iris produces tall, sturdy flowering stalks in late spring to early summer, showcasing large, showy blooms that are often purple or lavender in color with ruffled edges. After the blooming period, the plant sets seed and the flowers fade, with the foliage remaining green and photosynthetically active through summer and into fall before dying back with the arrival of winter. The rhizomes overwinter underground, going dormant until the following spring when the cycle begins anew with fresh growth.
Propogation
- Propogation time
  Late summer to early fall
- The most popular method of propagation for the Iris ensata 'Southern Son', commonly known as the Japanese iris, is through division of rhizomes. This is typically done after the flowering period in late summer to early fall. Gardeners should dig up the clump of iris carefully, then wash or brush off the soil. The rhizomes should be inspected and any that are old, soft, or showing signs of rot should be discarded. Healthy rhizomes with at least one fan of leaves can be cut apart with a sharp knife, making sure that each division has a section of rhizome and several inches of root. These divisions can then be replanted immediately in a new location, spacing them about 12 to 24 inches apart (approximately 30 to 60 centimeters) to allow for ample growing space. It's important to plant them at the same depth they were growing previously, with the top of the rhizome slightly exposed to the air.
